Consumption of red maple in anticipation of beech mast-seeding drives reproduction in Eastern chipmunks

Mathilde Tissier, Denis Réale, Dany Garant & Patrick Bergeron
1. Understanding the determinants of reproduction is a central question in evolutionary ecology. In pulsed resources environments, the reproduction and population dynamics of seed consumers is driven by pulsed production of seeds by trees, or mast-seeding. In Southern Québec, eastern chipmunks (Tamias striatus) exclusively reproduce during the summer before and the spring after a mast-seeding event of American beech. They thus seem to anticipate beech mast by reproducing during early summer, so that juveniles can...
